Aufgabe der vorliegenden Erfindung ist es daher ein Verfahren zur Herstellung einer Luftleiteinrichtung für einen Fahrwerkslenker und einen Fahrwerkslenker mit einer Luftleiteinrichtung bereitzustellen, die eine Steifigkeitserhöhung des Fahrwerkslenkers in Verbindung mit geringem zusätzlichen Gewicht ermöglicht.The object of the present invention is therefore to provide a method for producing an air guiding device for a suspension link and a suspension link with an air guiding device, which increases the stiffness allows the suspension arm in conjunction with low additional weight.
Diese Aufgabe wird für ein Verfahren zur Herstellung einer Luftleiteinrichtung für einen Fahrwerkslenker durch den Patentanspruch 1 und für einen Fahrwerkslenker mit einer Luftleiteinrichtung durch den Patentanspruch 8 gelöst.This object is achieved by a method for producing a spoiler for a suspension arm by the
Ein Verfahren zur Herstellung einer Luftleiteinrichtung für einen Fahrwerkslenker umfasst die folgenden Schritte:
- Bereitstellen eines Versteifungselements zur Anordnung an dem Fahrwerkslenker;
- Umspritzen des Versteifungselements mit einem Luftleitelement aus einem Kunststoff.
- Providing a stiffening element for placement on the chassis link;
- Encasing the stiffening element with an air guide element made of a plastic.
Indem ein Versteifungselement mit einem Luftleitelement aus Kunststoff umspritzt wird, entsteht eine hybride Luftleiteinrichtung mit an den jeweiligen Einsatzzweck angepassten Materialeigenschaften. So ist das Versteifungselement steifer als das Luftleitelement ausgebildet, um bei Anordnung an dem Fahrwerkslenker dessen Steifigkeit insgesamt erhöhen zu können. Das Luftleitelement hingegen benötigt keine hohe Steifigkeit, sondern sollte sogar eher elastisch sein, um Steinschläge oder andere anschlagende Objekte unbeschadet absorbieren zu können. Das Luftleitelement kann dementsprechend aus einem leichten und dünnen Kunststoff gebildet werden. Die Luftleiteinrichtung ist somit insgesamt leicht, verbessert aber bei Anordnung an dem Fahrwerkslenker dennoch dessen Steifigkeit.By a stiffening element is encapsulated with a plastic air baffle, creating a hybrid air deflector with adapted to the particular application material properties. Thus, the stiffening element is stiffer than the air guide element, in order to be able to increase its overall rigidity when arranged on the suspension link. In contrast, the air guide does not require high rigidity, but should even be rather elastic to be able to absorb rockfalls or other striking objects without damage. The spoiler can accordingly be formed from a lightweight and thin plastic. The louver is thus lightweight overall, but improves its rigidity when placed on the suspension arm.
In einer bevorzugten Ausführung des Verfahrens wird in einem weiteren Verfahrensschritt zumindest eine Aufnahme für ein Befestigungsmittel in das Versteifungselement eingebracht. Dieser Verfahrensschritt kann beispielsweise am Ende des Verfahrens erfolgen und als Bohrvorgang ausgeführt sein. Beim Durchbohren des Versteifungselements und eventuell auch des das Versteifungselement teilweise ummantelnden Luftleitelements kann eine gerade fluchtende Öffnung erzielt werden. Alternativ kann die Aufnahme bereits in das Versteifungselement eingearbeitet werden, beispielsweise beim Gießvorgang oder beim Umwickeln mit Kunstfasern.In a preferred embodiment of the method, at least one receptacle for a fastening means is introduced into the stiffening element in a further method step. This process step can take place, for example, at the end of the process and be carried out as a drilling process. When piercing the stiffening element and possibly also the stiffening element partially enclosing the air guide element can straight aligned opening can be achieved. Alternatively, the receptacle can already be incorporated in the stiffening element, for example, during the casting process or when wrapping with synthetic fibers.
In einer bevorzugten Ausführung des Verfahrens besteht das Versteifungselement aus einem Metall (Stahl, Aluminium, Magnesium, etc.). Ein metallisches Versteifungselement bietet gute Steifigkeitseigenschaften bei überschaubaren Kosten und geringem Bearbeitungsaufwand. Die zumindest eine Aufnahme für ein Befestigungsmittel wird in diesem Fall vorzugsweise als eine Durchgangsbohrung ausgeführt, da das metallische Versteifungselement besonders leicht spanend bearbeitet werden kann.In a preferred embodiment of the method, the stiffening element consists of a metal (steel, aluminum, magnesium, etc.). A metallic stiffening element offers good stiffness properties at manageable costs and low processing costs. The at least one receptacle for a fastening means is preferably designed in this case as a through hole, since the metallic stiffening element can be machined very easily.
In einer bevorzugten Ausführung des Verfahrens besteht das Versteifungselement aus einem faserverstärktem Kunststoff. Als faserverstärkte Kunststoffe eignen sich glasfaserverstärkter Kunststoff (GFK), kohlenstofffaserverstärkter Kunststoff (CFK) oder Kunststoff mit integrierten Kurzfasern. Diese Art von Kunststoffen sind deutlich leichter als die meisten metallischen Werkstoffe, jedoch steigen Kosten und Bearbeitungsaufwand.In a preferred embodiment of the method, the stiffening element consists of a fiber-reinforced plastic. Fiber-reinforced plastic (GRP), carbon fiber reinforced plastic (CFRP) or plastic with integrated short fibers are suitable as fiber-reinforced plastics. These types of plastics are significantly lighter than most metallic materials, however, increase costs and processing costs.
In einer bevorzugten Ausführung des Verfahrens umfasst die zumindest eine Aufnahme für ein Befestigungsmittel eine metallische Hülse. Die metallische Hülse wird dann benötigt, wenn das Befestigungsmittel mit Kunststoffen in Kontakt kommt, da sonst kein ausreichendes Anzugsdrehmoment aufgebaut werden kann. Zur Sicherung der Hülse in der Aufnahme können deren freie Enden umgebördelt werden.In a preferred embodiment of the method, the at least one receptacle for a fastening means comprises a metallic sleeve. The metallic sleeve is required when the fastener comes into contact with plastics, otherwise no sufficient tightening torque can be built up. To secure the sleeve in the receptacle whose free ends can be flanged.
In einer bevorzugten Ausführung des Verfahrens wird die Hülse während der Herstellung des Versteifungselements in dieses eingebettet. Eine mögliche Ausführungsform wäre beispielsweise die Hülsen in einer Vorrichtung an den vorgesehenen Positionen zu fixieren, um sie anschließend mit Kunstfasern zu umwickeln. Bei einer Vierecksanordnung der Hülsen können beispielsweise die diagonal gegenüberliegenden Hülsen miteinander durch Kunstfasern verbunden werden, so dass sich eine kreuzförmige Struktur des Versteifungselements ergibt. Die Kunstfasern werden mit Harz getränkt, das anschließend aushärtet.In a preferred embodiment of the method, the sleeve is embedded in this during the production of the stiffening element. A possible embodiment would be, for example, to fix the sleeves in a device at the intended positions in order to then wrap them with synthetic fibers. In a quadrangular arrangement of the sleeves, for example, the diagonally opposite sleeves with each other by synthetic fibers be connected, so that there is a cross-shaped structure of the stiffening element. The synthetic fibers are impregnated with resin, which then hardens.
Ein Fahrwerkslenker hat eine Luftleiteinrichtung, wobei der Fahrwerkslenker ein in Einbaulage nach unten offenes Querschnittsprofil, mit einer Basisfläche und zumindest zwei von der Basisfläche abstehenden Seitenstegen, aufweist und wobei die Luftleiteinrichtung ein Versteifungselement zur Anordnung an den Seitenstegen und ein Luftleitelement aus einem Kunststoff umfasst.A suspension link has an air guiding device, wherein the suspension link has a cross-sectional profile which is open in the installed position, with a base surface and at least two side webs projecting from the base surface, and wherein the air guiding device comprises a stiffening element for arrangement on the side webs and an air guiding element made of a plastic.
Indem die Seitenstege des nach unten offen ausgebildeten Fahrwerkslenkers (Pi-förmiges Querschnittsprofil) mit dem Versteifungselement der Luftleiteinrichtung verbunden werden, kann die Steifigkeit des Fahrwerkslenkers erheblich gesteigert werden. Das der Luftleiteinrichtung ebenfalls zugehörige Luftleitelement aus Kunststoff schließt sich dem Versteifungselement an und ist aerodynamisch ausgeformt, um in der Einbaulage des Fahrwerkslenkers im Fahrzeug eine gute Unterbodenumströmung zu erzielen. Der hybride Aufbau der Luftleiteinrichtung erzielt eine gute Versteifungswirkung bei gleichzeitiger Gewichtsersparnis.By the side webs of the downwardly formed chassis link (Pi-shaped cross-sectional profile) are connected to the stiffening element of the louver, the rigidity of the suspension arm can be significantly increased. The air guide also associated air guide plastic connects to the stiffening element and is aerodynamically shaped to achieve a good underbody flow in the installation position of the suspension arm in the vehicle. The hybrid design of the louver achieves a good stiffening effect while saving weight.
In einer bevorzugten Ausführung des Fahrwerkslenkers ist das Luftleitelement formschlüssig mit dem Versteifungselement verbunden. Der Formschluss ist bevorzugt durch ein Umspritzen des Versteifungselements mit dem Luftleitelement zu erreichen.In a preferred embodiment of the suspension link, the air guide element is positively connected to the stiffening element. The positive connection is preferably achieved by encapsulation of the stiffening element with the air guide.
In einer bevorzugten Ausführung des Fahrwerkslenkers ist das Luftleitelement kraftschlüssig zwischen Fahrwerkslenker und Versteifungselement gehalten. Durch das Einklemmen des Luftleitelements zwischen dem Fahrwerkslenker und dem Versteifungselement kann auf den Umspritzvorgang verzichtet werden.In a preferred embodiment of the suspension control arm, the air guide element is frictionally held between the chassis link and the stiffening element. Due to the trapping of the air guide between the suspension arm and the stiffening element can be dispensed with the Umspritzvorgang.
In einer bevorzugten Ausführung des Fahrwerkslenkers ist das Versteifungselement plattenförmig oder kreuzförmig ausgebildet. Die Kreuzform bietet bei gleichen Steifigkeitseigenschaften ein höheres Potential zur Gewichtsersparnis, als die einfache Plattenform.In a preferred embodiment of the suspension link, the stiffening element is plate-shaped or cross-shaped. With the same rigidity properties, the cruciform shape offers a greater weight saving potential than the simple plate shape.
In einer bevorzugten Ausführung des Fahrwerkslenkers weist das Versteifungselement zumindest eine Aufnahme für ein als Schraube oder Niet ausgebildetes Befestigungsmittel auf. Das Verschrauben des Versteifungselements erlaubt die lösbare Befestigung an dem Fahrwerkslenker, was Vorteile bei Reparaturen bietet. Der Niet kommt hingegen mit geringerem Bauraum aus. In allen Fällen sind jedoch abgewinkelte Enden der Seitenstege vorzusehen, in die die Befestigungsmittel eingebracht werden können.In a preferred embodiment of the suspension link, the stiffening element has at least one receptacle for a fastener designed as a screw or rivet. The screwing of the stiffening element allows the detachable attachment to the suspension arm, which offers advantages in repairs. The rivet, however, comes with less space. In all cases, however, angled ends of the side bars are provided, in which the fastening means can be introduced.
In einer bevorzugten Ausführung des Fahrwerkslenkers besteht das Versteifungselement aus einem faserverstärktem Kunststoff, wobei die Aufnahme durch eine metallische Hülse gebildet wird. Als faserverstärkte Kunststoffe eignen sich glasfaserverstärkter Kunststoff (GFK), kohlenstofffaserverstärkter Kunststoff (CFK) oder Kunststoff mit integrierten Kurzfasern. Bei der Wahl von Kurzfasern können Versteifungselement und Luftleitelement in einem Spritzvorgang erzeugt werden, wobei dem Versteifungselement zur Steifigkeitserhöhung Kurzfasern beigefügt werden. Die metallische Hülse wird benötigt, wenn das Befestigungsmittel mit Kunststoffen in Kontakt kommt, da sonst kein ausreichendes Anzugsdrehmoment aufgebaut werden kann. Zur Sicherung der Hülse in der Aufnahme können deren Enden umgebördelt werden.In a preferred embodiment of the suspension link, the stiffening element consists of a fiber-reinforced plastic, wherein the receptacle is formed by a metallic sleeve. Fiber-reinforced plastic (GRP), carbon fiber reinforced plastic (CFRP) or plastic with integrated short fibers are suitable as fiber-reinforced plastics. In the selection of short fibers stiffening element and air guide element can be produced in an injection process, wherein the stiffening element to increase stiffness short fibers are added. The metallic sleeve is required when the fastener comes into contact with plastics, otherwise no sufficient tightening torque can be built up. To secure the sleeve in the receptacle whose ends can be flanged.
In einer bevorzugten Ausführung des Fahrwerkslenkers ist das Luftleitelement schalenförmig ausgebildet und erstreckt sich in Querrichtung des Fahrwerkslenkers über diesen hinaus. Die Schalenform erzeugt neben den guten aerodynamischen Eigenschaften einen Schutz vor Steinschlag für den Fahrwerkslenker. Die genaue geometrische Ausgestaltung wird durch den Einzelfall bestimmt.In a preferred embodiment of the suspension control arm, the air guide element is cup-shaped and extends in the transverse direction of the suspension arm on this addition. The shell shape generates, in addition to the good aerodynamic properties protection against stone chipping for the suspension arm. The exact geometric design is determined by the individual case.
